摘要

以悬停姿态增稳控制系统为例,采用航空设计标准中的相关指标分析了某新型涵道式陆空车辆的飞行品质。参照军用旋翼式飞机设计标准ADS-33E-PRF,分析了响应带宽、轴间耦合特性和抗扰动特性。参照航天飞行控制系统设计、安装与测试标准SAE-AS94900,分析了特征值与稳定性裕量。采用H_1范数度量分析了多输入多输出(MIMO)系统的稳定性裕量和频域特性。分析结果表明除了滚转通道外,新型涵道式陆空车辆达到了期望的高性能飞行品质。
Based on attitude stability augmentation and control system in hovering condition,the flying qualities assessment for a novel ducted-fan air-ground vehicle is established.The design specifications,such as bandwidth,inter-axis coupling and disturbance rejection,are drawn from the Military Rotorcraft Aeronautical Design Standard ADS-33E-PRF,and the other specifications in terms of eigenvalue and stability margin are drawn from the Aerospace-Flight-Control-Systems-Design,Installation and Test of Piloted Military Aircraft SAE- AS94900.The H_∞ metric is also used to analysis the MIMO system stability margin and frequency- domain characteristics.The results indicate that top level performance is expected for all criteria utilized with exception of roll bandwidth where pilot induced oscillation(PIO) and level 2 handling qualities resulted.
